LOCKING DEVICE Filed May 29, 1962 F/G.7 Ha F765 1NVENTOR- w65 Z. A ya United States Patent O 3,157,040 LCKING DEVICE Royce L. Raye, 1652 Perryton, Dallas, Tex. Filed May 29, 1962, Ser. No. 198,515 ,f3 Claims. (Cl. 70-57) This invention relates to a locking device and has par ticul'ar applicability to a lock to be employed with any receptacle containing valuables, such as a vending machine, a lock box or the like.

A primary object of this invention is the provision of an improved substantially theft proof lock which incorporates means whereby exertion of force against the lock and its associated housing is exerted, and if the lock is ruptured, the stud or retaining pin will remain in position to prevent the opening of the receptacle.

A further object of this invention constitutes an improvement over my prior Patent No. 2,996,909, dated August 22, 1961, entitled Locking Device in that in the previous patent an annular groove about the end of the bar was employed, whereas in the instant invention the bore extends entirely through the bar, and a stud or pin engaging in said bar positively precludes removal of the bar or stud.

A further object of the invention is the provision of a device of this character which, when employed with a yoke and clevis surrounding a box, prevents the opening of the box upon breaking of fthe lock, since the locking pin is retained in engagement with the opening in the bar, to prevent disassembly of the yoke and clevis.

A further object of the invention is the provision of a device of this character which is sturdy and durable in construction, reliable and efficient in operation, and -relatively simple and inexpensive to manufacture, assemble, yand utilize.

Other objects will in part be obvious and in part be pointed out hereinafter and shown in the accompanying drawings wherein:

FIGURE ll is a fragmentary view partially in section and partially in elevation showing the locking device of the instant invention as applied to a yoke and clevis adapted to surround the box.

FIGURE 2 is a sectional View taken substantially along the line 2-2 of FIGURE 1 as viewed in the direction indicated by the arrows.

FIGURE 3 is a sectional view taken substantially along the line 3-3 of FIGURE l as viewed in the direction indicated by the arrows.

FIGURE 4 is a View of a bolt or bar disassembled from its associated mechanism.

FIGURE 5 is a plan view of a locking plug removed from its associated block Kand bar.

FIGURE 6 is an end elevational view of a stud, which may be positioned interiorly of a box or receptacle or the like, and to which the locking device comprising a part of the instant invention may be applied.

FIGURE 7 is a side elevational view of the device of the instant invention in operative position, the locking block being shown in dotted lines; and

FIGURE 8 is a plan view of the structure of FIGURE 7 before the application of a locking block or a similar locking device.

Similar reference characters refer to similar parts throughout the sever-al views of the drawings.

Having reference now to the drawings in detail, there 3,157,040 Patented Nov. 17, 1964 is generally indicated in FIGURE l a locking block 10, having a transverse bore. The vertical bore 12 is provided With radial slots 13, and has positioned therein a threaded plug 14 which includes a lock yand tumblers which extend tumblers 15 into slots 13 to prevent rotation of the plug. The lower end of the plug is threaded as at 16, and engages corresponding threads in bore 12. Obviously, after the tumblers 15 are extended, the plug cannot be unthreaded from its associated block.

The lower end of the plug 14 is provided with a stud 17 which engages in ya transverse opening or bore 18 in a locking bar 19. The locking bar 19 is best shown in FIGURE 4, and includes a head 20, which may be extended through aligned openings in a clevis 21 and a yoke 22 positioned about a vending machine, a strong box, or other like receptacle. In the employment of the device it will be obvious that when the key 23 is turned to extend tumblers 15, after threading the threaded end 16 of plug 14 itno the threaded lower end of bore 12, that rotation of the plug will be impossible. Due to the engagement of stud 17 in opening 18 it will similarly be seen that bar 19 cannot be withdrawn.

A modified form of construction is disclosed in FIG- URES 6, 7, and 8 wherein a Hat plate 25 provided with screw openings 26 is adapted to be positioned interiorly or exteriorly of a box or other receptacle 27 land secured to the inner side thereof. A central stud 2S projects from the plate 25 and is provided with a bore 29 which engages through an opening 30 inthe hasp 31 of a lock plate 32 hinged as at 33, and is adapted for the reception of a lock block 10 in the identical manner of the previously disclosed modification.

From the foregoing it will now be seen that there is herein provided a device which accomplishes all the objects of this invention and others including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative, and not in a limiting sense.
